Overview

Narva 3/8 compression fitting 57851 suits the Narva 57850 junction box where a 9.5mm cable entry fitting is required. It is the smaller round compression fitting in the 57850 junction box accessory group, suited to lighter cable entries where a larger 12.7mm or 19.0mm fitting is not the right match.

Features

• 9.5mm compression fitting.
• 3/8 inch diameter cable entry size.
• Made to suit the Narva 57850 junction box.
• Useful when replacing a missing, damaged or incorrect junction box cable fitting.

Compatibility and Fitment

Check the junction box model, entry port size and cable outside diameter before ordering. The main mismatch risk is choosing the 9.5mm fitting when the job needs the larger 12.7mm fitting, 19.0mm fitting, or one of the flat trailer cable compression fittings instead.

Compliance and Safety

Confirm the cable is seated properly through the fitting and that the compression nut is tightened evenly. Route the cable so the fitting is not carrying the weight of the loom, and add strain relief where vibration, movement or cable pull could stress the junction box entry.

Trailer Applications

Trailer workshops use compression fittings on junction boxes where lighting, auxiliary, brake control or trailer wiring looms enter an enclosed connection point. This 9.5mm fitting suits smaller round cable entries on the 57850 junction box and helps keep the cable entry mechanically supported at the box.
